The present application discloses a three-steering gear direct-drive coaxial rotor system and a control strategy, and belongs to the technical field of helicopter structures. The system includes an upper rotor power module, an upper rotor assembly, an upper tilting mechanism, a driving steering gear group assembly, a lower tilting mechanism, a lower rotor assembly, a lower rotor power module, an upper fixing mast, and a lower fixing mast. According to the present application, three steering gears directly drives an upper-layer swashplate and a lower-layer swashplate, to make cyclic pitch and add-subtract collective pitch on rotors. The synchronous tilting mechanism of the present application provides a flexible design solution for the characteristic of cyclic pitch phase angle offset of the rotors gear.
